After searching in the whole shop for the missing E-Drill Steel Bushing and not finding it i started searching all over again. The damn little thing is nowhere to find.
I asked Lucio for a possible alternative and he suggested to drill a AN4 bolt using a lathe....which i don't have. He commited to do that in the next week or so.
After few hours i decided to try myself using my drill press.
I started using a center drill and i determined the center of the bold using the hex head.
After that i inserted the bolt head down into the drill press. I positioned a very short #30 bit in the cross- table and i tried to have a correct vertical position.
I carefully drilled with a lot of lube and at the end i cut off the head and the threaded part of the bolt.
I repeated the whole drill for a second bolt obtaining a decent result.
After checking with Lucio the hole is acceptable in terms of concentricity and i will use the better bushing for the drill.
